Variables reserved for dynamic insertions

:ins_align
dynamic insertion
defines the manner in which the inline picture
  is aligned with respect to the line. Possible values: bottom, middle or top.
  Default is empty (which means bottom).

:ins_attr
dynamic insertion
is used to define miscallaneous attributes of a
  dynamic insertion. Examples:
  
  ins_attr = alt="meaning"
  or
  
  ins_attr = align=middle
  (aligns the middle of the image with the baseline for the current
  textline), or
  
  ins_attr = ismap
  (coordinates of the click will be passed back to the server; if the link
  of the element is the wims server, the coordinates will be registered
  under the variable ``no_name''.)
  $resetyes

:ins_border
dynamic insertion
is used to define border width of the html
  element ``IMG '' resulted from the dynamic insertion. Its value should be a positive
  number.
  $resetyes

:ins_density
dynamic insertion
is used to define the density of the dynamic
  insertions. Default value: ``100x100 ''.
  
  Avoid using this variable! We are planning to
  suppress it. Will be replaced by a server-managed variable.

:ins_format
dynamic insertion
can be used to determine the format of the
  graphics file of the dynamic insertion: its value should be either $emph
  gif'' or ``jpg''. The default value of this variable is
  ``gif'' (which can be changed by modifying the file $emph
  wims.conf''; but such change is not recommended). 
  Some types of dynamic insertions may not be affected by this variable.

dynamic insertion
 is used to define quality of the graphics
  convertion used in dynamic insertions. Its value should be between 0 and
  100. Affects only dynamic insertions whose graphics format is jpg.
